Chickens’ eyes are sensitive to the change of light. Chickens are affected by duration, intensity and spectrum of light. Lighting is one of the most important farming input on influencing the production of the meat, egg and other protein sources.
Chickens’ eyes are different from human’s, the light we perceive is the part of the electromagnetic spectrum our eyes can detect, known as the visible spectrum.
The same is true in animals, including poultry, but with one significant difference. The spectral sensitivity and visible spectrum of poultry, or what they actually see, is not the same as humans. It is why chickens may behave differently under the same intensity light from two different sources that look identical to us.
The most important is that the lights should be simulated the cycle from the sunrise to sunset.
